  • Title: Ratiometric fluorescence chemodosimeters for fluoride anion based on pyrene excimer/monomer transformation.
    Author: Gai L, Chen H, Zou B, Lu H, Lai G, Li Z, Shen Z.
    Journal: Chem Commun (Camb); 2012 Nov 11; 48(87):10721-3. PubMed ID: 23011510.
    Abstract:
    Two pyrene dimers containing an -O-Si-Si-O- or -O-Si-O- linkage have been designed which exhibit ratiometric excimer/monomer emission upon fluoride anion induced Si-O bond cleavage. Incorporation of the probe into water soluble polymeric nanoparticles enhances its intracellular uptake and displays ratiometric fluorescent sensing for F(-) in living cells.
